Obama can't "learn" how to be presidential in just over a week. He can't "learn" how to have an American heart. He's been clouded and infiltrated with muslim hatred his entire life. For half of his lousy life his mentor was that pig, Jeremiah Wright. Obama isn't smart enough to effectively pull it off.
Additionally, he's put all presidential responsibilities aside to TRAIN for tonight. It will be quite a show, my best guess. I look forward to it and wish him ill will in abundance.
obama ran out on the training for this night, same as he did last time. He wanted to have beer and pizza with his campaign workers.
